ABSTRAKT

The integral quantities measured on an arc heater where the electrical arc is stabilized by flowing gas serve as input data of a mathematical-physical model of phenomena inside the arc heater channel. The model is based on the mass and energy conservation equations and Ohm law and uses the known material properties of the gas medium. The main simplifying assumptions are LTE, relatively small kinetic energy of plasma, and axial symmetry of the investigated area. The main measured values are the arc current I (50 to 220 A), the arc voltage U (approx. 100 volts), the flow rate of the working gas G (argon, up to 22 g/s), energy loss of the arc heater channel Pz determined from the warming of the cooling water. By means of the mentioned model, the energy flows in axial (enthalpy flow) and radial (conduction and radiation energy loss) directions are computed and presented in diagrams.
